BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 508,509, dated November14, 1893. Applicationiiled March 23, 1893. Serial Nn.46'7,314. (Nomodel.)

To ald whom t may concern:

Be it known that I, DANIEL F. DooDY, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York,hav einvented certain new and useful Improvementsin Bottle-Stoppers, of whichthe following is a specification.

The object of myinvention is to provide av plug or stopper for bottles,jugs, demijohns, &c., Which while permitting the free discharge of theircontents prevents the refilling thereof; To accomplish this I provide aplug or stopper to be placed in the neck of the bottle, sufficiently farbelow its mouth to allow room for an ordinary cork.

The ldetails of construction and operation of my invention are setforthin the following description and in the accompanying drawings, ofwhich- Figure 1 is adetailed view of the neck of a bottle or othervessel in section, showing my improved device secured therein. Fig. 2 isa transverse section through my improved plug or stopper on thelines a:of Figs. 1 and 4. Fig. 3 is a detailed view of the plug at right anglesto that of Fig. 1. Fig. 4is alongitudinal section of the same on theline y y of Fig. 3, and Fig. 5 a detailed view of the valve withawasher. i

A indicates the neck of thebottle or other vessel having at a suitableydistance below or within its mouth, an annular rib a which serves topermanently secure the plug within the neck of the bottle as hereinafterdescribed. The plug, which may be made of one piece of glass or othersuitable material, and is provided with a valve that permits thedischarge of the contents of the bottle,but.prevents its refilling,maybe constructed substantially as shown and as follows:-It consists oftwo hollow cylindrical or tapering portions B O according as theinterior of the neck of the bot-` horizontal ribs are each opposite asolid portion d of the adjoining rib. In other words, the openings arearranged in alternation. irregularly shaped or tortuous passages arethus formed in the outer face of the part B. Each of the projections d,below the upper ones, iscentrally recessed as at d', opposite theopening between the portions d of the adjoining horizontal ridge nextabove. All Lthe openings between the parts d of each horizontal ridgeare preferably formed with f inclined side walls, the openings beingwidest at the top. The upper ends of the bars D may, as shown, form therecessed projections in the lower row. The lower portion O of thelstopper is formed with a valve seat E on which is seated the valve E.The stem above the valve extends up between the two bars D D and isprovided with three radially projecting wings e that Work in and areguided by the lower portion of the interior bore of the part B, whilethe stem below the valve is formed with similar projections e that Workin and are guided by the bore of the lower portion O.

It Vwill now, be obvious that if such a stopf tle has been filled, ifthe bottle is inverted the `pressure of its contents will unseat theValve and the contents will enter the space Y from whence it will passthrough the irregular or tortuous passages on the exterior of B and bedischarged from the mouth of the bottle. Any attempt to refill thebottle, however, will fail because any liquid passing down through thepassages in the exterior of B will at once seat the valve and beprevented from entering the bottle. When the plug has been inserted andsecured as presently described or otherwise, the bore of the part B isclosed by a stopper F, which maybe cemented therein by liquid glass, orother suitable cement so that it may not be removed. To facilitate theinsertion of this stopper, it may have a lug or projectionf formed uponit so that it can be held by a pair of pliers and properly put inposition. Insteadof the lug f, it might of course have one or morerecesses in its face for the same purpose. 'The mouth of the bottle maythen be closed byan ordinary shipping cork as indicated in dotted linesat G Fig. 1. A y

It is obvious that after the contents of the bottle have been dischargedas already described, the bottle cannot be refilled because it is notpossible to hold up the valve. To prevent any one from doing this is thepurpose of the peculiar formation on the exterior of the part B. It willbe noticed that any wire or instrument which one might attempt to insertthrough the openings c would be obstructed by the projections d and theend of the wire would be caught in the recess d and in anyevent would beso deiiected that it could not be brought into engagement with thevalve. At the same time the contents ot y the bottle may be freelydischarged.

If the valve E and its seat E are properly faced, no washer will benecessary, butl prefer a washer and by further preference such a one asis indicated in the detailed view, Fig. 5. In thisiigure the Iiexiblewasher H which may be of rubber or any other suitable material, is ofconcavoconvex shape, its concave face being next the valve seat. Itsedges are preferably free as shown, and its central portion is securedto the under face of the valve. Such construction insures a perfectlytight tit of the valve upon its seat and even if the valve did notdescend properly upon its seat, should an eort be made to retill thebottle, the pressure of the fluid upon theloose edge of the washer wouldclose it against the seat.

In order to secure the stopper within the neck of the bottle thefollowing construction may be adopted,though of course it might becemented in or secured in any other suitable manner. The exterior faceof the part C is tapered from its lower end inwardly to a shoul- Theannular space thus formed may be tilled with a suitable cement and thenwhen the stopper is forced into its place the annular rib a on the neckof the bottle, will force the cement I', which is indicated by the blackshade in Fig. l, around and below the rib a upon which the shoulder Ithen rests. As soon as the cement has set the stopper will be rigidlysecured in the neck of the bottle and cannot be removed. Instead ofcement an elastic ring of any suitable material may be used inconnection either with the rib a or an annular channel within the neckof the bottle into which the elastic material would expand and lock thestopper.

I claim as my invention- 1. A stopper for preventing the refilling ofbottles, consisting of upper and lower portions adapted to be seated inthe neck of a bottle, the upper portion having horizontal channelsconnected by transverse openings alternately arranged, and a stopper forclosing its bore and the lower portion being provided with anautomatically acting valve that permits the discharge of the contents ofthe bottle, but is closed whenliquid is poured Vinto the bottle.

2. Abottle stopper consisting of two tubular portions having betweenthem a liuid space (Y), the upper portion having exterior tortuouspassages formed by horizontal channels connected by alternately arrangedopenings, in combination with a plug or stopper for the bore of theupper portion and a valve seated in the lower portion, and the radialarms projecting from the valve stem on each side of the Valve, and lyingin and guided by the bores of the upper and lower portions,substantially as set forth.

3. A bottle stopper consisting of upper and lower portions, the upperportion beingformed with tortuous passages on its exterior face, andhaving a stopper for closing its bore, in combination with a valveseated in the lower portion and having a washer secured upon its face,but free at its edges. y

4. In a bottle stopper, the combination of the parts B C, part B havingtortuous passages on its exterior face, and a plug for closing itscentral bore,a valve seated in the portion C and having its stem workingin and guided by the bores of both portions B and C, and aconcavo-convex iiexible washer secured upon the face of the valve andfree at its edges. A

5. The combination of the bottle stopper, substantially such as hereindescribed having its lower portion tapered, so as to form an annularshoulder and a consequent angular annular recess a filling of cement orbinding material surrounding said tapered portions and filling saidrecess and a bottle or other vessel having within its neck an annularrib or locking surface with which the cement or binding material engagesand against which said shoulder abuts when the stopper is in place.

6. A bottle stopper, substantially of the character herein described,having upon its exterior face aseries of projections d. formed byhorizontal channels connected by transverse openings the face of eachprojection lying opposite one of said openings, being recessed for thepurpose described.

7. A bottle stopper consisting of upper and lower portions, and anintermediate fluid space (Y), the upper portion having tortuous passagesin its exterior face, and a plug for closing its bore having upon itsouter end means by which it may be held while being inserted into place,and an automatically operating valve seated in the lower portion.

In testimony whereof I have hereunto subscribed my name.

DANIEL F. DOODY.
